Siblings Swim for Survival After Boat Sinks in St. Lucia

Two siblings swam for more than half a day, battling huge waves and fearing sharks after their fishing vessel capsized.

Dan Suski, 30, of San Francisco, and his sister Kate Suski, 39, of Seattle, chartered a boat last Sunday and had planned for a day of fishing in the waters off St. Lucia. A captain and first mate also came along for the excursion.

The 31-foot fishing vessel suddenly took on water Sunday afternoon, forcing all four people on board to strap on their life jackets and jump into the open water.
